Do you snore loudly at night? Do you wake up tired even after 8 hours of sleep? You might have sleep apnea, a condition where your breathing stops and starts repeatedly during sleep. But here is something many people do not know: not all sleep apnea is the same. There are different types, and each one needs a different kind of treatment.
In this article, we will explain the main types of sleep apnea, how they are different from each other, and which sleep apnea treatment options work best for each type. Whether you are newly diagnosed or just trying to understand your condition better, this guide will help you.
What Is Sleep Apnea?
Sleep apnea is a sleep disorder where your breathing repeatedly stops during sleep. These pauses can last a few seconds to more than a minute. They can happen dozens or even hundreds of times per night.
When your breathing stops, your brain gets less oxygen. Your body wakes itself up just enough to restart breathing sometimes, so briefly that you do not even remember it in the morning. Over time, this pattern takes a serious toll on your health, increasing your risk for high blood pressure, heart disease, stroke, diabetes, and more.
Sleep apnea is more common than most people think. Millions of Americans have it, and many do not even know it. The first step to getting better is knowing which type you have.
The 3 Main Types of Sleep Apnea
1. Obstructive Sleep Apnea (OSA) — The Most Common Type
Obstructive sleep apnea is by far the most common type. It happens when the muscles in the back of your throat relax too much during sleep. This causes the airway to become narrow or completely blocked. Air cannot flow through freely, so your breathing stops.
Think of it like a garden hose that gets kinked. The water (air) cannot pass through until you straighten it out. In OSA, your brain sends a signal to your muscles to tighten up and reopen the airway — and you briefly wake up, often with a gasp or snort.
Common signs of obstructive sleep apnea include:
- Loud, chronic snoring
- Gasping or choking sounds during sleep (often noticed by a partner)
- Waking up with a dry mouth or sore throat
- Morning headaches
- Daytime sleepiness, even after a full night of sleep
- Difficulty concentrating or staying focused
OSA is more common in people who are overweight, sleep on their backs, have a large neck, or have a family history of the condition. However, even thin, active people can develop OSA.
2. Central Sleep Apnea (CSA) — A Brain Signal Problem
Central sleep apnea is less common and works differently. In CSA, the airway is NOT blocked. Instead, the brain simply fails to send the right signals to the muscles that control breathing. There is a communication breakdown between the brain and the body.
People with CSA often do not snore as loudly as those with OSA. Instead, they may experience repeated awakenings, shortness of breath, and difficulty staying asleep. Unlike OSA, there is no physical blockage the problem starts in the nervous system.
Central sleep apnea is more often linked to serious medical conditions like heart failure, stroke, or the use of opioid pain medications. It can also occur in people living at high altitudes.
3. Complex Sleep Apnea Syndrome — A Combination of Both
Complex sleep apnea syndrome, also called treatment-emergent central sleep apnea, is when a person has both obstructive sleep apnea AND central sleep apnea at the same time. This type is usually discovered when a patient starts CPAP therapy for what was believed to be OSA, and central apnea events begin to appear or worsen.
Because complex sleep apnea syndrome involves both types, it requires a more specialized treatment approach. Standard CPAP alone may not be enough. It is important to work closely with a sleep specialist who can monitor your response to treatment and adjust it accordingly.
Mild, Moderate, or Severe: Why Severity Matters Too
Besides the type of sleep apnea, doctors also classify sleep apnea by severity based on how many breathing pauses you have per hour, which is called the Apnea-Hypopnea Index (AHI).
- Mild sleep apnea: 5–14 breathing events per hour
- Moderate sleep apnea: 15–30 breathing events per hour
- Severe sleep apnea: More than 30 breathing events per hour
Mild sleep apnea treatment often starts with lifestyle changes and oral appliance therapy. More severe cases usually require stronger interventions like CPAP or surgery. Knowing your severity level helps your doctor choose the right treatment path for you.
Obstructive vs Central Sleep Apnea: A Quick Comparison
Understanding the difference between obstructive and central sleep apnea is key to getting the right treatment. Here is a simple side-by-side comparison:
Obstructive Sleep Apnea (OSA):
- Cause: Physical blockage of the airway
- Snoring: Usually loud and frequent
- Who gets it: Anyone, especially those overweight or have certain anatomies
- Treatment: Oral appliances, CPAP, surgery, lifestyle changes
Central Sleep Apnea (CSA):
- Cause: The brain fails to send the correct breathing signals
- Snoring: Less common or absent
- Who gets it: People with heart conditions, stroke, or opioid use
- Treatment: ASV therapy, CPAP variants, and treating the underlying condition
Sleep Apnea Treatment Options: Which One Is Right for You?
The good news: Sleep apnea is very treatable. But the best treatment depends on the type you have, how severe it is, and your personal lifestyle. Here is a breakdown of the most common sleep apnea treatment options available today.
1. Oral Appliance Therapy (Dental Sleep Medicine)
Oral appliance therapy is one of the most comfortable and convenient obstructive sleep apnea treatments available. A custom-fitted dental device, similar to a mouthguard or retainer is worn during sleep. It gently moves your lower jaw forward to keep your airway open.
This option is ideal for people with mild to moderate OSA, especially those who cannot tolerate CPAP machines or who travel frequently. Oral appliances are quiet, portable, easy to care for, and very effective for the right candidates.
At Eagle Falls Dentistry in Bloomingdale, our dental sleep medicine team specializes in custom oral appliances. We work with your sleep physician to design a device that fits perfectly and keeps your airway comfortably open throughout the night.
2. CPAP Therapy (Continuous Positive Airway Pressure)
CPAP is the most well-known and widely used treatment for moderate to severe obstructive sleep apnea. It works by delivering a continuous stream of air through a mask worn over your nose or mouth. This air pressure keeps your airway open all night long.
CPAP is highly effective and is often the first-line recommendation from sleep doctors. However, some people find it uncomfortable, noisy, or hard to sleep with. If you have tried CPAP and struggled, do not give up. Other options may work better for you, including oral appliance therapy.
3. Lifestyle Changes for Mild Sleep Apnea
For mild sleep apnea treatment, lifestyle modifications can make a significant difference — sometimes even resolving the condition on their own. These include:
- Weight loss: Losing even 10% of your body weight can reduce OSA severity significantly
- Positional therapy: Sleeping on your side instead of your back
- Avoiding alcohol and sedatives: These relax throat muscles and worsen apnea
- Quitting smoking: Smoking increases inflammation in the airway
- Regular exercise: Even without weight loss, exercise can improve OSA
4. Positional Sleep Apnea Treatment
Some people have positional sleep apnea — their apnea is much worse when sleeping on their back. For these patients, positional sleep apnea treatment focuses specifically on keeping them off their backs during sleep. Special devices, pillows, or even wearable positional trainers can gently encourage side sleeping. This is a simple but surprisingly effective solution for a large number of OSA patients.
5. Inspire Therapy — A Newer Option for OSA
Inspire therapy for sleep apnea is an exciting, newer surgical treatment for moderate to severe OSA in people who cannot tolerate CPAP. It involves a small implantable device similar to a pacemaker that is placed under the skin in your chest and neck during a minor outpatient procedure.
The device monitors your breathing during sleep and sends gentle electrical impulses to the nerve that controls your tongue and airway muscles. When it detects an apnea event, it stimulates the muscle to keep the airway open. You control it with a small remote. There is no mask, no hose, and no noise.
Inspire therapy is not for everyone; it has specific eligibility criteria, but for the right patients, it can be life-changing. If you are interested in learning more, speak with a sleep specialist or your dentist about whether you qualify.
6. Central Sleep Apnea Treatment Options
Because central sleep apnea has a different cause, a brain signaling problem, its treatment is also different. Standard CPAP may actually make CSA worse in some cases. The most common central sleep apnea treatment options include:
- Adaptive Servo-Ventilation (ASV): A type of PAP therapy that adjusts in real-time based on your breathing patterns
- BiPAP (Bilevel Positive Airway Pressure): Delivers different air pressures for breathing in and out
- Treating the underlying condition: If CSA is caused by heart failure or another illness, treating that condition often improves the apnea
- Supplemental oxygen: Sometimes used alongside other therapies
CSA is typically managed by a team of specialists, including cardiologists, neurologists, and sleep medicine physicians. If you suspect you have central sleep apnea, it is important to get a thorough medical evaluation.
How Is Sleep Apnea Diagnosed?
The only way to definitively diagnose sleep apnea and to find out which type you have is through a sleep study, also called a polysomnography. This can be done in a sleep lab (in-lab study) or at home with a home sleep apnea test (HSAT). During the study, your breathing, oxygen levels, heart rate, and brain waves are monitored while you sleep.
Your dentist can play an important role here, too. At Eagle Falls Dentistry, we screen patients for signs of sleep apnea during regular dental visits. Signs like worn teeth, a scalloped tongue, a small jaw, or enlarged tonsils can all be clues that point toward OSA. If we see these signs, we can refer you to a sleep specialist for a proper diagnosis.
The Role of Dental Sleep Medicine in Sleep Apnea Treatment
You may be surprised to learn that your dentist can be one of your most important partners in treating sleep apnea. Dental sleep medicine is a growing specialty that focuses on using oral appliances to manage sleep-related breathing disorders, especially obstructive sleep apnea.
A specially trained dentist can evaluate your mouth, jaw, and airway, and fit you for a custom oral appliance if you are a good candidate. This appliance works by gently repositioning your jaw during sleep to keep the airway open. It is a great alternative or complementary therapy to CPAP for many OSA patients.
At Eagle Falls Dentistry in Bloomingdale, Illinois, our dental sleep medicine team works collaboratively with your physician. We can help with screening, appliance fitting, and follow-up care — all in a comfortable, friendly dental office environment.

Frequently Asked Questions About Sleep Apnea Types and Treatments
Q: What is the most common type of sleep apnea?
A: Obstructive sleep apnea (OSA) is by far the most common type, accounting for the majority of all sleep apnea cases. It happens when the soft tissues in the throat relax and block the airway during sleep.
Q: Can sleep apnea be cured?
A: In some cases, yes. Significant weight loss, anatomical corrections through surgery, or treating an underlying medical cause can resolve sleep apnea. However, for most people, it is managed long-term with a combination of lifestyle changes and therapy.
Q: Is CPAP the only treatment for sleep apnea?
A: No. While CPAP is a common and effective treatment, it is not the only option. Oral appliances, positional therapy, weight loss, Inspire therapy, and surgery are all viable alternatives depending on the type and severity of your sleep apnea.
Q: Can a dentist treat sleep apnea?
A: Yes! Dentists trained in dental sleep medicine can provide oral appliance therapy for obstructive sleep apnea. At Eagle Falls Dentistry, our team can screen you for sleep apnea and fit you for a custom oral device that helps keep your airway open while you sleep.
Q: How do I know if I have central or obstructive sleep apnea?
A: The only way to know for sure is through a sleep study. Your doctor will analyze your breathing patterns during sleep and determine whether your apnea events are caused by a physical blockage (obstructive) or a brain signaling issue (central).
